RESUMO
The mean uterine dimensions [length, transverse and anteroposterior diameters] in 53 normal nulliparous women were ultrasonically estimated to be 71 mm, 49 mm and 32 mm, respectively. In 40 normal multiparous women they were 77 mm and 37 mm, respectively, while in 32 grandmultiparous women [para >5] they were 83 mm, 60 mm and 42 mm, respectively. There is significant increase in all uterine dimensions with increasing parity. In 23 women with clinical polycystic ovary syndrome [PCOS], the uterine dimensions were 66 mm, 43 mm and 30 mm, respectively. The uteri of these women had significantly smaller length and transverse diameters than normal nulligravidae. A uterine length of 70 mm or less and a transverse diameter of 42 mm or less were significantly commoner in PCOS cases than normal nulligravidae. This may be an additional helpful ultrasonic measurement in the diagnosis of PCOS
